Making sense of Math | Greg Tang | TEDxAmoskeagMillyard

Imagine finding simple solutions to seemingly complicated math problems and enjoying it, too. Math educator and author Greg Tang offers three cues – visualization, reasoning and number sense – to break down equations and preconceived stressors in ways that will take away bad memories and provide new solutions and a chuckle or two along the way.

Greg Tang is a Math educator and author.

I will be teaching math this year for the first time in 10 years.... thank you for taking the fear out of it for me. I’ll keep getting better at it so my students love it this year.

I love this guy, who cares about sound quality!! He is a rock star!!! I have paid hundreds of dollars to see this presentation in person. You are fortunate to find it on YT!

[marynnalindseykerce]

Yay! Greg Tang's children's books are outstanding. I am so happy to be able to share his talk, as well. Thank you

[MegaSquiff]

Went straight into the ‘watch later’ file. This is for viewing more than once. Both educational and fun. A big thanks.

[geensjc]

this is what I needed in school! now I have to try MAKE SENSE of math while studying my teacher degree. this was an awesome TEDx Talk - THANK YOU

[illsuive]

Thank you Greg. You described me from beginning to end and i'm going to be applying these tools you've shared.

[babypichu]

So fascinating!
I'd never thought of Math like that.

[yurniwati]

Brilliant, you give me new pespective of mathematics

Instead of breaking 790 into 700 and 90 (to divide by 2) and then juggling 350 and 45 in your head, which is way too many digits for my tiny skull, it goes much easier if you break 790 into 800 and minus 10: you get 400 and minus 5 which is 395.

I did it via 700 and 90 in my head when he showed it on the screen, then the smoother road occurred to me afterwards.

so good - thank you Greg Tang for your great work!!!!

Mr Tang is addressing people with a certain level in maths. A level much higher than mine.

[AndrewFalgout]

As a parent this helps. Nothing more frustrating with my kids coming home and asking for help and being told by my kid that I'm not doing it the way the teacher wants it done.
Also.. on the subtraction, If they don't learn the traditional method of borrowing then doing math outside of base 10 would be harder to learn I imagine. Octal or Hex math for instance would not work this way.

[calculusfan]

I already use some of those ideas. It would be interesting to see how he would approach harder problems like the equations and fraction problems that don't have nice whole number answers.

[zgunderson]

I did exactly what you're explaining and I got in trouble for not showing my work

[ahmedAltariqi]

It's hilarious how the audience make me feel like they've mistaken this for stand-up comedy!

[MarthaDora]

Fear is out. Everything makes sense now.

[Abbas_AliG]

What if we do it this way
30 is 3\6 of what number
We divide 30 with 3 which will give us 10 and then 10 multiply by 6 is 60
I mean what if we avoid x which is alphabetical representation of a number and just focus on the arithmetic operations which are far easier to comprehend and teach

[roneysunil]

Thank you sir so much, I have a weird sense of satisfaction.

[vinayseth]

3:58 Another way is to imagine a cube, since 27 is a cube number.

How did I get from the attack on Titan opening to here?
